Astronomers may have found giant alien 'megastructures' orbiting star near the Milky

You know we always fantasize about alien attacks on humanity but when we can't even show respect to our own species because of a different skin color or religion, what do you think we'd do to entire different alien race?

If they can build a Dyson sphere like speculated orbiting around the recently identified star, the question is what do they do to the lower forms of life on their planet?

[Urbanized]

Yeah, if that is a Dyson Sphere, they have zero reason to fear us.

I agree with the above. It's far more likely that we would not be superior to an alien life form. I think most humans for many years have come to that conclusion. That's why every extra-terrestrial themed movie, show, documentary, etc. is always portrayed as Earth being on the defensive and not the offensive.

The only movie I can think of where it was opposite is Avatar, where Earth is trying to harvest the subtlety named "Unobtanium."

No luck in the radio search, so far.
